History clamping for denoising dynamic ray-traced scenes using temporal accumulation
Approaches presented herein can reduce temporal lag that may be introduced in a generated image sequence that utilizes temporal accumulation for denoising in dynamic scenes. A fast historical frame can be generated along with a full historical frame generated for a denoising process, with the fast historical frame being accumulated using an exponential moving average with a significantly higher blend weight. This fast history frame can be used to determine a clamping window that can be used to clamp a corresponding full historical value before, or after, reprojection. The fast historical blend weight can be adjusted to control the amount of noise versus temporal lag in an image sequence. In some embodiments, differences between fast and full historical values can also be used to determine an amount of spatial filtering to be applied. |

A unified access layer (UAL) and scalable query engine receive queries from various interfaces and executes the queries with respect to non-heterogeneous data management and analytic computing platforms that are sources of record for data they store. Query performance is monitored and used to generate a query performance model. The query performance model may be used to generate alternatives for queries of users or groups of users or to generate policies for achieving a target performance. Performance may be improved by monitoring queries and retrieving catalog data for databases referenced and generating a recommendation model according to them. Duplicative or overlapping sources may be identified based on the monitoring and transformations to improve accuracy and security may be suggested. A recommendation model may be generated based on analysis of queries received through the UAL. Transformations may be performed according to the recommendation model in order to improve performance. |

Probabilistic risk assessment for trajectory evaluation
Techniques are discussed for evaluating trajectories based on risk associated with the trajectories with respect to predicted locations of objects in an environment. A vehicle can capture sensor data of an environment, which may include object(s) separate from the vehicle, such as another vehicle or a pedestrian. A prediction system can output a discretized probability distribution comprising prediction probabilities associated with possible locations of the object in the future. Heat maps, as an example discretized probability distribution, can represent one or more objects. Trajectories can be generated for the vehicle to follow in the environment. An overlap between a region of the vehicle along a trajectory and the heat map can be determined, and a probability associated with the overlap can represent a risk associated with a trajectory navigating through the environment. The vehicle can be controlled based on risks associated with the various trajectories. |
